Room for improvement in data handling leads to enhanced cost-effective data management performance
It would be beneficial if MongoDB Atlas could better support OLTP aspects and data frames, as well as enhance its capabilities for data pipelines and visualization dashboards. Furthermore, supporting the medallion architecture could be a valuable addition, and incorporating improved spatial and vector handling for geographical data could make it more competitive. Enhancing vector processing for AI capabilities would also be critical.
Shrikant Navelkar - PeerSpot reviewer
Have achieved excellent performance and seamless integration with effective cost control in cloud solutions
When customers are migrating from Oracle Exadata Express Cloud Service and need to remove some of their test and development environment, what happens in normal virtualization is that they can just switch it off, but in ExaCS, they need to terminate the entire thing. Most of the customers are not aware of this, so they keep spending money even if they want to shut down their UAT environment or development environment, so Oracle needs to make it simpler in terms of reducing the bill on ExaCS when customers want to shut down certain environments. Today, you have to terminate the entire VM, and only then your billing will stop. The only functionality I would expect from Oracle Exadata Express Cloud Service is that if Oracle is able to support Oracle MySQL Enterprise also on Exadata, that will solve a lot of problems.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It can store data as a flat file, similar to a file system."
"The dynamic structures are the most valuable."
"The stability and performance are great. The high availability feature is great. Moreover, I am happy with the automated backup and restore functionality."
"The price of MongoDB Atlas is reasonable, which is why many organizations, including mine, are opting for it."
"Its most valuable features are high availability and zero maintenance."
"The most valuable feature is that it's all web-based. So one can browse collections just from the web. MongoDB Atlas is very accessible, quick to understand, and quick to learn. People who have never used CLI can hop into the web interface and browse the database."
"The features that I have found most valuable include the very easy integrations. The integrations are fantastic. I have not faced any challenges from the integration standpoint."
"The speed of it is the most valuable feature."
"In the cloud, Exadata is more scalable. The on-prem version was limited. It wasn't that scalable because it only came in a quarter rack, half rack, and full rack. In the cloud, it scales to what you need."
"Having the prediction happen in the modular format allows you to start with a lower version of Exadata and then you can keep on upgrading it as per your requirement."
"The performance of the tool is valuable."
"I highly recommend Oracle Exadata Express Cloud Service as a very good solution if you can afford it."
"One of the most valuable parts of the solution is the high availability within the system and the performance enhancement without making any changes or fine-tuning the databases."
"I like that Oracle Exadata Express Cloud Service is easier to use and is a cost-saving solution because you won't need to hire people to run and maintain it."
"I would rate Oracle Exadata Express Cloud Service ten out of ten for its overall solution."
"It is a scalable product."
 

Cons

"There are some features that could be useful for the customers I work with, which are related to migration from on-prem to the cloud."
"Customer support needs improvement knowledge-wise."
"The speed when combining two documents is concerning."
"MongoDB Atlas should add more APIs in their Terraform module because sometimes I find it difficult to find the resources in their Terraform model."
"The cost needs improvement. The product is good, but the cost that we paid for it is expensive, so it wasn't that valuable."
"I would like the solution to offer more integration capabilities since it is an area where the solution lacks."
"We had some bad trainers when we first came onboard and would rate them fairly low. They did not seem staffed properly to fulfill the training services that they offered."
"The installation was straightforward except for the network hardware because it was a little complicated to make the connection with our VPC on AWS."
"We use artificial intelligence for deep learning, and it would be a huge benefit to implement this in Oracle Exadata."
"Scaling Oracle Exadata Express Cloud Service can be done, but the process is a little tedious, which could be an area for improvement in the solution."
"The support must be faster."
"The only downside is the difficulty in monitoring, and that's why I would like to implement MySQL database."
"The product's installation process needs improvement. It could be more accessible."
"The customer's default choice is the on-premise version of this solution. Only when Oracle or the partners like us, can explain to customers the cloud value proposition, and if the compliance authorities allow, they can look into this cloud solution. It will take some time for Oracle to change its perception of customers' de-facto standards. Exadata used to be treated as a black box, which is not the case now. The customer is aware of what is happening inside, how the configurations have been made, and what patching has been applied. Oracle needs to market the cloud version better."
"The solution's pricing could be improved."
"I feel there is a need for better integration with Google Maps and Google Earth. This is crucial for me in the geographical facilities of the environment."
 

Pricing and Cost Advice

"We're currently using the Atlas for the night and don't require a license. However, it can be a problem if you want to use their enterprise environment. Then you need to purchase the license."
"The pricing is acceptable for enterprise tier."
"The pricing is good. We originally chose it over DynamoDB because of the pricing."
"Comparing the price between the MongoDB and Microsoft SQL Server, we are using the enterprise edition of Microsoft SQL Server, which is more expensive than MongoDB."
"The solution is fairly priced. I rate the pricing a seven out of ten."
"I have seen the cost, and it was pretty cheap."
"The tool is free since it's an open-source product."
"It is an open-source platform."
"I think Oracle pricing is usually above average market price."
"The price of this solution is very comparative to others on the market. There is no direct comparison between this solution and with something else because I do not see any other similar product."
"The tool is not cheap, but it is not really expensive."
